CVE-2026-5304 in Axis OS
Summary
by MITRE • 08/11/2026
An ACAP configuration file lacks input validation, which could potentially lead to privilege escalation. This vulnerability can only be exploited if the Axis device is configured to allow the installation of unsigned ACAP applications, and if an attacker convinces the victim to install a malicious ACAP application.

This vulnerability represents a critical security flaw in Axis network video surveillance devices that leverages the ACAP (Axis Camera Application Platform) framework to potentially enable privilege escalation. The core issue stems from insufficient input validation within the ACAP configuration file processing mechanism, which creates an attack surface where malicious actors can manipulate application installation parameters. According to CWE-20, this vulnerability maps directly to improper input validation, a fundamental weakness that allows attackers to inject malicious code or configuration data into the system. The vulnerability requires specific preconditions for exploitation, including the device being configured to permit installation of unsigned ACAP applications, which typically represents a misconfiguration that reduces the device's security posture.
The technical flaw manifests when an attacker crafts a malicious ACAP application that exploits the lack of validation in the configuration file parsing process. This allows the attacker to manipulate the application's privileges or execute arbitrary code with elevated permissions that would normally be restricted. The vulnerability operates at the application level within the Axis device ecosystem, where legitimate applications are expected to run with specific privilege boundaries. When an attacker successfully installs such a malicious application, the system's access control mechanisms fail to properly validate the application's intended privileges, potentially allowing the malicious code to escalate its privileges beyond what was originally permitted.
The operational impact of this vulnerability extends beyond simple privilege escalation to encompass potential complete system compromise and unauthorized data access. An attacker who successfully exploits this vulnerability could gain administrative access to the surveillance device, enabling them to modify video feeds, disable security features, or extract sensitive information from the device's storage. This threat is particularly concerning in security-critical environments where Axis devices are deployed for monitoring purposes, as it could allow adversaries to maintain persistent access to surveillance infrastructure while remaining undetected. The vulnerability also represents a significant risk to the integrity of video evidence and the overall security of networked surveillance systems that rely on proper privilege separation.
Mitigation strategies should focus on both immediate operational controls and long-term architectural improvements to prevent exploitation. Organizations must ensure that ACAP application installation settings are properly configured to only allow signed applications from trusted sources, effectively closing the attack vector that enables this vulnerability. According to ATT&CK technique T1068, privilege escalation through application installation requires proper access control enforcement, which should be implemented at multiple layers of the device's security architecture. Network administrators should regularly audit device configurations to ensure that unsigned application installation is disabled unless absolutely required for legitimate operational purposes. Additionally, implementing network segmentation and monitoring for unusual application installation activities can help detect potential exploitation attempts, while regular firmware updates from Axis can address known vulnerabilities in the ACAP platform implementation.
